11-09-20 the brightest gamma ray beam ever created -- more than a thousand billion times more brilliant than the sun -- has been produced in research led at the university of strathclyde, and could open up new possibilities for medicine. physicists have disc...
11-09-19 a research team at michigan state university has developed a laser that could detect roadside bombs -- the deadliest enemy weapon encountered in iraq and afghanistan. the laser, which has comparable output to a simple presentation(描述) pointer, p...
11-09-14 researchers at vanderbilt university have developed a new technique that uses a single uv laser pulse to zap(攻击,打败) away biological tissue at multiple points simultaneously, a method that could help scientists study the mechanical forces at w...
11-02-18 more than 50 years after the invention of the laser, scientists at yale university have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. the discover...
10-12-22 december is a time for twinkling lights, and scientists at the department of energy's thomas jefferson national accelerator facility are delivering. they've just produced a long-sought, rare color of laser light 100 times brighter than that generate...
10-09-27 portable devices with painless laser beams could soon replace x-rays as a non-invasive way to diagnose disease. 带有无痛激光束的便携设备可能将迅速取代x射线成为诊断疾病得力工具。 researchers say that the technique could become widely available in abo...
10-09-03 protecting helicopters in combat from heat-seeking missiles is the goal of new laser technology created at the university of michigan and omni sciences, inc., which is a u-m spin-off company. battlefield terrain(地形,地势) in places like afghanis...
10-03-29 tiny chemical sensors implanted into patients could help diagnose disease and track its progress, following a development by scientists. researchers have developed tiny probes comprising gold-coated particles. these can be inserted into cells, enabl...
10-02-22 for nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized x-ray laser that could, among other things, provide super high- resolution(分辨率) imaging. and for the past two decades, unive...
09-09-09 us military researchers are developing a method for communication that uses lasers to make sound underwater. 美国军方研究人员正在研究一种使用激光在水中发声的通信方法。 the approach could use commercially available lasers the approach focuses laser l...
